seq: zero gets padded if specified with scientific notation

[cakebaker]

I noticed that if I specify zero with scientific notation (and without specifying -w), the zero gets padded. With GNU seq, there is no padding:

$ cargo run -q seq 0e15 1
0000000000000000
1
$ seq 0e15 1
0
1

I would like to work on this issue if it's not already being handled.
